Sir, it's quite possible this asteroid is not entirely stable. Do those files that are not saved belong to the project?

Hehe, threw me off for a second there with that first sentence...

Anyway, just ran code blocks again to check and files are now auto saving as usual. But I'm quite sure the files belonged to the active project when the error came up as the project compiled fine (with the changes to source that is) when I manually saved the files before compiling.

Strange that I can't reproduce the error now. Hmm, maybe a case of staying up too late coding? :wink:
